The eye can be examined with relative ease as to both its function and its structure. A functional assessment consists of the ability to relocate the orbit and the response of the pupil to light and accommodation.
The function of the eye may be evaluated in numerous methods. The client might be asked to identify illuminated letter or objects of differing sizes on what is called the Snellen chart.
Conversely, the evaluation of the structural part of the eye may be made in numerous methods. Tension within the eyeball is determined by a "tonometer." In specific illness, particularly in glaucoma, the tension in the eyeball is increased markedly.
It should be well remembered that a client with an eye problem might have other problems. Frequently other physical conditions are primary and impact the eye as a repercussion. The appearance of the eye can signal the physician and the patient to troubles in some disturbances of other parts of the body even before other symptoms present themselves.
As a result, one's reliance on sight is emphasized when one deals with a possible or short-lived long-term loss of this crucial sense. When restorative procedures are looked for, particular forms of vision correction such as contact lenses or glasses are prescribed.
On the other hand, some people are bothered with the truth that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were established to motivate reduced utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Generally, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgery is another kind of vision correction. The only distinction is that with this type of surgery, one's vision is remedied permanently.
With LASIK eye surgical treatment, the refractive errors in the cornea are permanently transformed. This can be done using an "excimer laser."
The main function of this surgery is to produce a threadlike, rounded "flap" in the cornea utilizing a address blade understood as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, allowing much better the eye to direct more light into the retina.
Popularity vs. Disadvantages
In the middle of the growing popularity of LASIK eye surgery, there are still disadvantages that people must understand. Probably, the main reason this kind of eye surgical treatment has actually become well accepted is due to the fact that many of its cases had succeeded.
However, in spite of its success, there are still some drawbacks. Here is the list:
1. It is an operation applied to the most sensitive part of the eye
Since LASIK eye surgery includes the operation of the retina, which is among the most delicate portions of the eye, view the majority of people say that the operation can be very dangerous.
In other words, a easy mistake could nearly trigger an person's life time blindness. Thus, it is necessary to think about many aspects before choosing whether LASIK eye surgical treatment is the ideal restorative measure one needs to undergo.
2. It is not a ideal procedure
LASIK eye surgical treatment may correct your vision but it does not always mean that it can give you a perfect vision. Even if statistical reports reveal that 70% of the clients may image source have 20/20 vision, this does not necessarily imply they have ideal vision also.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK may not always be the ideal eye surgical treatment the way the majority of people see it
Conversely, the evaluation of the structural part of the eye might be made in several methods. It should be well kept in mind that a client with an eye problem might have other problems. Frequently other physical conditions are main and impact the eye as a effect. The appearance of the eye can inform the client and the doctor to problems in some disruptions of other parts of the body even prior to other signs provide themselves.
Like its concrete counterpart, LASIK eye surgery is another form of vision correction.
